I completely understand I have followed from the beginning. Maybe take some time away and reasses the car and throw a ton of emotional $$ in there.
I have sold some meaningful cars over the years and even if you try to re- do it it never feels the same.
If ROI is your concern (I realize it isn't)then it probably wasn't a good purchase in the first place all the years you have kept that car are worth more than anything that just has more fun pedal.
Not to mention what is owed to the car for serving you all this time
.
There are very few cars I can say I would like to have back but the only one that sticks out in my mind is my 69 Camaro b/c of all the stress relief it gave me
second to that was my little LUV pickup it was ratty as hell but was just too much fun.
I'm putting some stock into this little Mule more and more as time goes on and I think it is starting to rate right up there. Hell I may even put some work into it cosmetically and forget the swap into the newer 944.
BTW... OT but did you ever send off the MAF unit?
I think I may have some insight to the problems you were having.
