As a buyer, A salesman is your best friend.

As a customer looking for repairs/warranty work/or to make complaints, They are as helpful as a fert in an elevator!

I remember years ago, My dad looked at this car at a large showroom, he asked to see the log book and made a note of the owners details and in the documents found his phone number.

Once at home my dad rung the previous owner and asked him basic questions.

All in all he was helpful and did buy the car in the end.

There is no harm in asking questions before parting with your hard earned cash!

I have had MOT's and issues have been pointed out that next years didn't it just says something about the MOT system.

A service could just be a Oil and filter change and nothing more. So the dealer my well be correct about the facts provided.

With regards to MOT advisories.

Dads car was MOT'd 2 years ago, on the certificate the garage advised that the front tyres were barely legal. I had checked them before the MOT and they were fine, had 3mm left across the whole tyre. Shortly after changed fronts and rears round, the fronts now had 4 mm, the rears 3mm. At last years MOT both front and rears had 3mm and guess what, no advisory. They will be changed before this years MOT, 2 years after the advisory and still legal.

I got an advisory on my car about 6 years ago. Stated that the Hazard switch was illuminated when the lights were on. Strange but that is what is supposed to happen, helps you find it in the dark. Once activated it flashes. Tester would not have it, said to get it fixed. The next year, same garage, different tester, no comment. 5 years later original tester again and he commented about the switch but did not put on as advisory. Total idiot.
