bad credit car leasing advice

[Clydesdalestu]

Hi,

I wonder if anyone can help me?

I am about to sell my car, which is 4 years old and has dropped form £37k list price to around £13-14k resale value! As such, I have learned my lesson about buying cars and would like to lease instead.
However, due to a marriage breakup (which saw my wife run off and leave me with over £40k of debt, which at the time I could not service)I have been left with an adverse credit history (although I have made great steps to clear this up and now only have £13k outstanding - however 3 CCJs still show on my file).
I have spoken to a few online "specialists", who have proposed that I may be able to get some form of deal, but it is likely to be for a car around the value of £15k at best.

Does anyone know of any:
a) Brokers that would look the best deal out for me, for a commission
b) Companies that would offer me a wider choice of vehicles, with a higher value (cars I am looking at are in the £30k bracket)
c) Companies that lease pre-owned vehicles
d) Companies that lease prestige cars, but would be willing to deal with someone in the sub-prime category.

I have a very good job, earn considerably above average salary, could pay a substantial deposit and can demonstrate an excellent financial record since the debt was allowed to default. In short, I'm one of the good guys, who got dropped into a situation!

Any advice welcome,

Cheers!
