They'll all break and need to be maintained and I feel if you want it, go for it!!!! I grew up with mostly Chevy cars and trucks and wanted a '68 Chevelle for my first car because we had one a couple years earlier. It was a 2 door, 327, 3 on the tree and it was a couple years old when we got it. There was a '66 4 door Fury III, every model of '57 Chevys, many 55s, some 58s, and several Impalas. Several International Travelalls and many Chevy trucks. There were even some foreign vehicles in there.
My dad and grandfather came across a '65 Sport Fury, this was June 24,1979 so the car was only 14 years old and never messed with (like a 2010 now, not a big deal). The jack was in place and some extra tires were in the trunk, the skirts were on it as well as the spinner hubcaps. I purchased it on the 25th and drove it home for $100. There's a thread on here under restorations I started in 2018. I've built many vehicles through the years for others and myself, and I'd rather build a GM product. I feel there's more support from the aftermarket for many GM and many Ford vehicles. At this time I'm helping a friend with his '67 Chevelle convertible and he has purchased every body panel he needs new including an SS hood. Another friend is building a '70 GTO convertible and has done the same thing. I've only had to do minimal work (if any) to make the panels fit just right, much less time than fixing rust!!! With Mopar I've found minamal new panels and when I find good used parts, the cost takes the fun out of it and when it comes to moldings, forget it!!! These guys can get everything new. I had to make my own quarter panels because the only ones out there completely suck!!! I'm glad my car was in amazing shape when I got it and not too bad when doing it over this time. The aftermarket support is getting better for us building Mopars, but our one year only parts just aren't out there yet. I feel mixing brands is great, they all have pros and cons and we can fix some of the cons!!! If I'd have ended up with a '68 Chevelle, I'd be building it the same way I'm building the Fury, the way I want it to be!! Good luck!!
