ORIGINAL: Fen I think you'll struggle even more if you want to pick and choose the buyer, Ben. I know exactly how you feel - I joked that I wanted a covenant on the woodwork in our house when we sold it as we had spent so long stripping it all back (stairs, floors, doors, architrave; you name it it was stripped), but realistically if the people who bought it have painted it all bright blue that's OK because they gave us their money and that's what we really wanted. In terms of your car as a package it's neither one thing nor another if I'm honest. Even if it's truly the best 944 you've seen in condition the value in that would be originality which requires a bone stock 2.5 engine. On the other hand if the 3.2 is the ultimate money no object engine upgrade it should really be backed up with a money no object approach to everything else that can be upgraded (suspension and brakes primarily) or the car is an unfinished project. Lastly the bonnet scoop, tinted windows and lights are basically chav mods almost exclusively seen on cars that are in sight of the car park in the sky. To make the last point worse you are an exceptionally young chap to have such a car and most of your prospective buyers will be a good 10-20 years your senior. Speaking as a member of that age group I know I'd be more comfortable dealing with someone older, times 10 when I'd just seen the bonnet, windows and lights on the car. Please don't think I'm saying that for any reason than to try to help you see it as others would. If you want/need to sell the car then I want you to do that and get the best price possible for it, but to do that you need to see it as a potential buyer would, not with a judgement coloured by your emotion and intimate knowledge of the project. I'm actually in the same situation as you in a lot of ways in that I have a car for sale that is massively modified from standard, that has cost me hugely more than it will ever be worth and that now appeals to a very narrow market. What I have done with mine is try to make the package cohesive by which I mean that all the modifications follow the same theme, so in my case if it isn't necessary it's removed and if there is a better part than standard then it gets replaced. I haven't taken that to its absolute conclusion (there's no cage and the sunroof is still in place for example), but it's mostly done and hopefully there is nothing significant that would put off someone in the narrow market the car appeals to. You can't do a lot about being young, but you need to work all the harder to make the car dispel any worries someone might have about buying it from a "young lad". If I were you (and I assume you really are committed to sell the car in the following, otherwise just keep it), I'd replace the bonnet and then advertise the engine but leave it in the car until I found a buyer (so they could drive the engine). I'd also get it dyno'd to make the most impressive set of figures and plot I could for use in the ad (using a decent dyno that people will believe, probably Thorney's as that's where Evo go these days, certainly not the "washing machine" or similar). Once sold I'd use the money to fund a replacement engine with basic cheap tuning to the 290-310bhp level and look to sell the car with that for mid-market money.
