Cool car! I like these more than I should, and they look cool, like a Japanese Jaguar, but not the best choice in a Japanese car. Mechanically, it's basically a 300ZX sedan
The VG30DE has a timing belt, and it is also hard to work on. A lot of parts aren't available for it. For example, you can't get shocks for it (OE supplier was Tokico). The J30 also has surprisingly little room inside and a tiny trunk too. The 93 doesn't have heated seats or keyless entry, and timing belt interval is only 60k. It went to 105k starting in 94.
Not a good idea to buy something obscure when money is tight
