$1400 isn’t too much to spend to fix up an old car. I have an acquaintance who - about 5 years ago – he purchased a 1967 VW Beetle in almost perfect condition. He wanted to re-live his hippie days I guess. The engine had been rebuilt, the upholsterly redone, and the car repainted. It wasn’t perfect, the paint job was of questionable quality, especially on the wings and near the running boards wasn’t quite done right, and wasn’t an original VW color, some of the engine parts and suspension parts really should have been replaced with newly manufactured versions which are available from VW speciality shops, and the tires should have been whitewalls like the original, and the hubcaps weren’t the orgiginal round shiny ones, but it was still pretty good, looked good overall. And ran fine. I think this VW Beetle, 40 years old, it cost him $9000. The first thing he did was take it apart. Seriously. Engine and transmission out. Seats out. Everything that could be taken apart, apart. To almost the last nut and screw. He sanded. And rust-proofed. New wiring harness. Rebolted. Repainted. It cost him another $8000, and that’s just in parts and the labor he didn’t do himself. But he’s happy with it now, and that’s what’s important.
So $1400 isn’t too much to spend on an old car. But it IS too much to spend on THIS car, if all you need is a replacement exhaust pipes and muffler and can re-use the existing cat. If you have to puchase a new cat, then $1400 would be reasonable. Very reasonable in fact. Cats made to the manufactuer’s OEM spec’s are very expensive.
