To be fair though none of you really know me? If I'm here asking for a spec me a 335i your no better positioned apart from a few internet posts which tell you what I want you to see.
The guy can basically save at £1k per month, he has a total of £18k at the moment. He wants a very fast, very flashy car, soon. He has no other unusual financial situations and will not consider a loan or new car.
He has no kids, a GF and rarely needs his car to ever carry anything big so he can have a 2, 4, 5 or 7 seater.
He assumed a Boxster S would cost £1k a month to keep on the road and I said for that surely a 911 is a much better bet - but it's gonna take him another 8 months to save for that.
