LHD to RHD
John,
Sorry, I don't know the answer to the particular question on changing from LHD to RHD, maybe somebody else has done it? I would think if doable your $20k would make it happen, that said the other part of your equation is the tough part........a good one at $45k
I agree with Polaris that if its a good car it will do better than that, even a RHD in the UK. Then you have shipping duty etc....it would be nice, but I don't think realistic.
What I do think is realistic is leaving it as a RHD, why not, you keep the value, there is no problem brining it in to the US and it is always the CSL it was supposed to be, therefore no discount for the change.
I would have somebody check the car though, it has obviously had some changes throughout the years and the fact he mentions waxoil in boot is worrying. There is a possibility that it is Waxoyl in its purest sense or it may be somebody using a generic term for a boot full of black gunk, ie undercoating.
Pictures are not great, but trunk is out of alignment and seat material is wrong, beyond that its tough to tell condition.
Good luck to anybody thinking of buying, its a great color.
