The Toyota Yaris Mk1 May Seem Boring At First, But It Has A Slight Bit Of Potential. The Specs On A 1.0 16v VVT-i GLS Is 67Bhp, A 0-60 Of 13.7 Sec And 137g/km. This Car Can Reach 485 Miles On A Full Tank, Has An Average MPG Of 41 Miles, And The Road Tax Per Year Can Reach £200, But Many Have Low Tax, So Don't Worry About Such A Price. The Weight Of One Of These Is Just 865Kg! Also, The Top Speed Is 97Mph. Not Too Fast, But You Can Find Many Examples Well Under Even £1K! If You Want To Modify One Of These, You Will Still Stay Under The £5K Mark. Mods Include:

The Mk2 Corsa Is A British Icon On The Road. You See Them Everywhere. They Are Like The British Version Of The American Toyota Camry. However, This Car Is Not As Nearly As Impressive As The Camry, Packing A 1L Petrol Engine That Produces Just 57 Bhp, And Can Do A 0-60 In A Very Slow, 16 Seconds, There Is Some Good Too. This Car Is Perhaps The Most Efficient Car On This List, Reaching An Average MPG Of 51 Miles Per Gallon, And Can Do 493 Miles On A Full Tank! It Also Has The Lower Price For Road Tax, Of At Most £180. However, This Price May Be Deceiving, As The Value Of The Car Itself Can Just Be Double, If Not Triple The Road Tax, So It Must Be Much Lower. This Car Also Has Aftermarket Support For Body Kits Mainly. However I May Be Able To Find Some Performance Upgrades Too, As 57 Bhp Isn't Very Head Turning. So Here Are 2 Links For Mods!:
