Looks like a good price for an entry level collectable, but then maybe not https://www.hemmings.com/classifieds/dealer/buick/skylark/2229143.html
O.K. here's what I can see ... Hood fits badly at top of grill, bad paint poor prep where paint meets vinyl roof and lower lf. quarter looks to be touched up with a different Blue.
Vinyl top is wrong grain and stitching, headlamp bezels are body color, steering wheel came from a parts store, grill is I don’t know what, rear seat upholstery wrong, front looks funny, blower switch is ‘69, wheel center caps wrong, trunk paint is a mess, underhood is too. There’s a lot of hours and dollars needed to bring it up to asking. If it runs perfect it’s $10k too high. Patrick
