Rich, The answer is both. I got the yellow one in 1994 , the white one in 2007. They are both London Roadsters ,factory assembled on IRS VW pans with slightly tweeked engines.The yellow one is the original gelcoat and the white one has been repainted but was originaly yellow also.The man I got it from said the 1’st owner died soon after buying it and it sat for years before he found it and reworked it. They both have black tires now. I too spend a lot of time comparing the cars on this forum . Some time I think I would like to sell them both and get a front engine BCW .
Thanks for your interest, Larry M.
