+2. Those are homemade...looks like copper pipe. Probably be better than the OEM plastic ones, lol! But you can find them, eBay usually has a decent supply.
Rust- check rockers, rear fenders, front control arms, brake lines. These are all problem areas.
Check for smoke. The car has high mileage but not anything too absurd, but smoke is a sign of a blown turbo. $1500 is a little high for a car with that mileage, but its balanced out by the hardtop.
Does it come with the hardtop removal tool?
Drop the back seat and check the condition of the soft top under the hardtop. (lock panel inside driverside doorjam) It'll be hard to see.
If its trashed, see if you can knock the price down a couple hundred. Replacements can be had for $200 but they're a little tough to install yourself
