what you have to ask is why the first one was resprayed... as stated its been turboed, and has P plates on it... stay away

The second one has P plates, had the original rims sprayed, and has an exhaust... its been messed with, i'd stay away

The third one is exhausted... but looks otherwise stock, which leave it open to someone who has demodded it to sell...

You havent told us what kind of car you are looking for... if i was you id be looking to buy one as close to standard as possible, and certainbly wouldnt buy off a P Plater... If you dont mind km's and who has owned it... take a look for obvious panel damage (unless the owner is upfront and tells you if its had any) check the dipstick ffor fresh oil, check log books for regular servicing, and general condition of the car...

But yeh it really depends on what you want... its very hard to find an unmolested one these days, and i wouldnt pay a premium for a car that has been modded at all.
