I have never & will never source a car for anyone, if it's something I'd buy anyhow then I've bought one & one the few occasions I've offered it it has never been what they wanted - they ALWAYS want something else OR they then check their insurance with the inevitable result.
2 tales;
I once suggested (to a reasonably wealthy friend wanting a daughter's first car in the £3K range) that he gives me a list of MUST HAVES and MUST NOT HAVES, I'd tell him the maximum price, he'd then have to take the car or he would forfeit the deposit - which I said would be £500. This is a man who is NOT tight-fisted, who I've looked after his home when he was earning big bucks abroad, throws me the keys to his expensive car, we drink together, known each other for decades but when it came to the subject of a non-refundable £500 deposit you'd of thought I'd threatened to rape his daughter.
A V70 D5 I bought & advertised normally. A flurry of interest. One chap says he definitely wants it cos it's bright red. I answer it's shiny but I'd describe it as a wine red. Anyhow, I confirmed the colour name to this Volvo "expert" (if memory serves it was something like Ruby Red Metallic) and even gave him the colour code. The old chap drives 200 miles to be with me by 9am on the Saturday morning. He sits for a few seconds clearly "having words" with his wife and gets out with a face like thunder - clearly he's not happy. To cut a VERY long story short, we get into an argument over the colour & eventually he gets his copy of the advert that he'd printed. LO & BEHOLD!! HIS PRINTER WAS FAULTY & MY RUBY RED CAR APPEARED BRIGHT RED WITH A BLUE HALO AROUND IT & BROWN TYRES!!!!
When he still continued to chew-on (about 15 minutes of me being polite in deference to his age) I showed him the advert on my phone and eventually had to point out that "NONE OF MY CARS COME WITH A BLUE HALO & BROWN TYRES. YOU ARE WRONG, IT'S YOU WHO'S FUCKED UP NOT ME". I pressed his Mrs. for an answer, laughed in his face & told him to leave.
So Matt, if you REALLY fancy risking your redundancy go for it. But honestly, please DON'T.
