Did you just land in to see the other 2 cars without prior appointment and ask for a test drive in the first few mins? Or did you discuss the vehicle with the seller and the faults, if some one finds fault in my vehicle or doesn't like it, they normally say, nothing worse than the usual "i'll have a think" line, its alot better if folk say what the issue is so it can be rectified.
First one no appointment (Hurst's) second one appointment, it was in Ballymoney so a fair drive for me. I did ring them both the next day to say I wasn't proceeding. Both good enough cars as said but the 3rd represented the best value/condition/history.
The one in Ballymoney incidentally was advertised with a full service history, confirmed on the phone. What it actually consisted of was a ford stamp at 9k and a random stamp 4 years later at 37k. Why do people do this?
If the cars are properly presented and the customer just wants to drive it to see what a 'golf' drives like as they may consider buying one sometime, I would class that as a total time waster. Thankfully I'm not in the position to have to sort those out from the genuine customer.
