Ivan: a boxer engine fan moving on to inline 6? hmm... it's quite hard to get people to offer you a rare classic like this. Usually people who owns this type of ride would rarely wanna part with it... u gotta really look hard and search everywhere for it..
Try to find a good chassis if you can. Engine wise it can be rebuilt or be replaced by another from a salvage yard... Chassis is truly important as that's the foundation of your ride. If you get one that's either twisted or rusted beyond repairs then it will be pointless as your other options to this would be quite 'not so legal'.
All in all, i wish u good luck ya? :) oh ya, another thing, there's no ideal price to a ride of this stature... it all depends on how much u r willing to pay for a ride that you love... but of course it's all cash but i doubt it would be an issue for a young CEO like yourself. Don't mind kevin, he has this tendency to ensure people's pocket is safe... lol
