When I was looking for a 5 series I went to the local Arnold Clarke garage. They didn't have one in stock, but I told the salesman the amount I was willing to spend, the model and year I wanted, mileage range, colour/s, all the usual stuff.
After faffing about for the best part of an hour trying to sell me a Merc and running off to talk to his boss about 5 times I left saying when you find me the car I'm after call me as I would definitely be buying it ( as long as it met what I had stated).
That was in March..... I'm still waiting on a phone call.
I seen the exact car I was after the following week at an Arnold Clarke dealership in Penrith. I rang them on the Saturday , they emailed me detailed pics, I arranged a test drive for the following day, done the deal on the same day and picked the car up on the Wednesday !
So what was the salesman in Dumfries playing at? Didn't try very hard to get my business.
And another thing, local guy offered me £300 for my 02 plate MV6 , immaculate condition with FSH and 73k on clock. £300!!

! Not a chance matey. The guy in Penrith offered me £1000.
