Some general advice about car shopping.
If searching online watch out for scams... A common car one is to sell it very cheap and say you have to use their shipping company/escrow site. If its too cheap it's a scam.
Oh, if you have any doubts about it you can drop me a PM, i scam bait as a hobby so am pretty good at spotting them.
Hmm, if you go to a dealer, ask for the lowest price they can give you on a car, say your asking around all the dealers and the lowest one gets your money, no haggling, just taking the best price. That's a lie, always go back round saying that a different company offered you £50 or less than the best deal.
Always be prepared to walk away. If a seller really thinks you want a car, they have the upper hand.
Also, with the credit crunch coming, it's pretty much a buyers market.
