Some rookie questions about a GN

498 Views 3 Replies 2 Participants Last post by  cew
Im looking to buy an 85 Grand National, Pretty much needs a total resto, except for the engine has 25,000 on it s rebuild. Is 1500 a good price? It has T-tops, and 3 minor rust spots. Been sitting for about 8 years, outside! One main question I have. Whats the difference between this year and others, like the 86 or 87 GN? I know its not intercooled. Can i add an intercooler? The front and rear plastic bumber parts are missing too. What will this cost me roughly? What are some good places to buy aftermarket, and what should i know about this car before i buy? Any help for be greatly appreciated! You can post or e-mail me at [email protected]

hey, before you do anything,pop out the t-tops,
you said it's been sitting outside for 8 years,
look very closely at the area where the t-tops sit, around the weatherstripping, especially in
the corners by the a- pillar and above the windshield, also down by the upper door hinges on
both sides, check for the traditional cracks in the b- pillar, try popping the back seat out, to check rear pan,especially under the opera windows
also does it seem to run correctly? i know you said it had a rebuild, does the tranny shift? does it run, i've seen more than a few of the hot-airs turn into nothing more than a parts car with alot of new parts and sensors. just double check.if it runs & drives & is'nt a complete bucket, $1500 is'nt bad. also check bottom edge of doors. a side note, i had an 85 with the t- top seating area was rotten,badly. cutting the roof off and making it a hardtop was a cinch as
compared to the repair possibilities, no more leaking t- tops,you can also use a monte,grand prix,or cutlass roof.should be able to get one at a boneyard for 40 to 100 bucks. you can intercool it but it is'nt cheap and the piping is long unless you swap it over to 86-87 style
alot of work(fun though)and again not cheap.
some vendors amongst the many good vendors,
atr ,postons,modern musclecar,ogs,caspers,i could go on.i hope it's a diamond in the rough
for you, they are out there,good luck.
