I advertised an old car I had that I took to a classic car show. Made nice little signs gave it the detail of it's life and a service and everything.
BUT
That day was made of fail!!!!!
My car drummed up a bit of interest, most of the people who were most interested were about when I left the show (or at least I tried to) the fucker conked out infront of everyone in the que to get out, then I couldn't get it started again (carbs were flooded) and when I did it conked again (then the fuel gauge decided it was buggered) so it seemed I'd ran out of fuel on a steep hill with an inoperable handbrake and about 100 cars stuck behind me with no way past.
In the process of getting it started I nearly rolled backwards into a car worth more than my house and the guy inside was shitting himself. All the while I had 'helpful' people walking past trying to tell me what to do with the choke etc (on an engine I built myself...badly) who promptly fucked off when they could have been some help when I ended up getting my new girlfriend (I'd met a week previous) to get out and push in a short skirt.

.....perhaps they just wanted to watch.
But the fun didnt end, I got some fuel.... this guy gave me a drip (literally) from a jerry can for £3 (I paid him before he gave me the fuel (big mistake) which was enough to waft me over the hill to a petrol station but it ran out as I drove into the station less than 300 yards away (so I was charged £1 per 100 yards

) I went to pay for the fuel and my card was not working in the cashiers machine so my missus had to pay to fill it up.
Anyways. would I sell a car at a show again?.........that experience put me off.
I fucked that car off to someone with more money than sense in the end but the gf is still around 8 years later so that's something.
