you did check that you have the key for the locking nuts? only just published Autoexpress All Season Tyre Test 2015 http://www.autoexpress.co.uk/accessories-tyres/92863/all-season-tyres-test-2015-top-all-weather-tyres-tested

Wayne, where are you? ffs it's hours since we last heard from you. I hope you didn't get lost and head North on the motorway to Scotland because they Scotnats are out celebrating the independence anniversary as if they'd won it or something. If you come across the border you'll see loads of they wee McGonks running about with their claymores and sporrans and pibrochs just dying to pounce on a Sassenach.

That's one test figure I'd really like to see although it's probably impossible now I guess... I'd like to see the difference in mpg with the Prius when the only factor that changed was that drag coefficient from 0.27 down to 0.25 (without changing the wheel size/shape) by just changing body shape. Or in other words, what, in mpg terms, does a drop of 0.02 directly equate to? Is there such a figure anywhere?

Those bulb are sometimes used with rubberised sheaths which provide the chosen colour. These can, with care, be swapped over to the replacement clear bulbs.

When I was specing my car up, it was the Icon+ with 16" alloys and 85g/km CO2 or Excel for more money with 17" alloys, 88g/km, worse ride and worse MPG. As the 16" alloys looked fine it was a no brainer not to go for the smaller wheels.

As well as the differences on CO2 and mpg quoted for the Gen T3 and the T4/Spirit Prius, the drag coefficient goes up from 0.25 to 0.27. Whilst it's possible extra equipment may weigh slightly more, the only external difference is the wheel/tyres, which I think are wider with the 17" ones, hence increased frontal area. Some early Gen 3 owners with 17" wheels said they didn't fit nicely under the boot floor after they'd had to use the space saver - 15" ones do! On the Gen 3 Prius, heaven knows how many millions were spent getting the CD (drag factor) down from 0.26 on the Gen 2 to 0.25 on the T3 (and later the plugin - both 15" wheels). Toyota claimed at the launch that the Gen 3 had the highest amount of wind tunnel testing of any Toyota in history. Then they fitted 17" wheels to the T4 and T-Spirit, which lifted the CD back to 0.27 - WORSE than the Gen 2 !!! - with the consequent hit on mpg, CO2, comfort and replacement tyre cost for owners!

Yoy mis-read him - he IS saying that the wheels DO affect the MPG; However it has nothing to do with the size if the overall radius (i.e. wheel + tyre) is the same. What he's saying is that it's purely down to the weight - A 17" alloy is going to weigh a significant amount more than a 15" alloy, and that is all unsprung rotating mass. I read somewhere that 1kg of unsprung mass is equivalent to 4kg of sprung mass in terms of its effects on MPG, and assuming that's true I figure the effect on mpg between 15" and 17" is near that of carrying a concrete slab or two in the back of the car Just a small amendment; You don't have to go for Mag Alloys for light weight - Aluminium is good enough. However, almost all OE manufacturers use cast alloys, which are only slightly lighter than equiv steel wheels because the alloy is weaker than steel and more material has to be used. Forged aluminium wheels, however, tend to be massively lighter; When I bought PaulT's old 14" Toyota alloys off him, he was showing off the Rays Engineering forged ally wheels he'd bought to replace them and they were so light you could lift them with one finger! However the cost was an order of magnitude more than what I paid him for the Toyota alloys, so you pays yer money as they say ;)

It's not the OBD socket, it's under the dash at your right knee.

Grey imports brought into the UK do not have their details recorded by Toyota GB, and are not traceable should any recall action be required. The only way for owners of Grey Imports to establish whether their vehicles may be affected by any recall action, is for the owners to contact the Toyota GB Contact Centre directly. Contact details for the Toyota GB Contact Centre are: Telephone - 0344 701 6202 Opening Hours - 8:30am – 6:00pm Monday – Friday, and 9:00am – 1:00pm Saturday The Toyota Contact Centre is able to provide information and support to resolve your query quickly and effectively. Calls to this number cost the same as calling an 01 or 02 number, where calls to 01 or 02 numbers are part of any “inclusive” minutes (on mobile or landline), calls to this number will also be included. Post - Toyota (GB) PLC PO Box 814 Portsmouth PO6 9AY United Kingdom Owners of Grey Imports in other countries should contact their local Toyota Distributor.

Martin, They chose to go with a reversing camera rather than parking sensors. All I want is a camera that is useful. I'm not asking them to install something extra like sensors ( as good as they are), just to install a camera that works.

Eygo, Sadly they don't actually say that the Aygo has lines, it just implies they do. I.e. They just keep to the right side of the law. I think the only way to get results is to bombard Toyota with comments on the aforementioned blog. Mike

Search for trim tools on eBay, about £3, basically just orange plastic tools which I found very helpful in places particularly around the air vent area. I'll try put a pic on
