Buy-risk rundown
| Issue | Symptom | How to check | Typical cost (as of Nov 2026) |
|---|---|---|---|
| Timing belt + water pump (interference C30A/C32B) | None until failure — then bent valves | Demand dated invoice; calendar matters on low-mile cars | Belt/pump/tensioners/seals commonly ~$1,800–$3,500; full hose-inclusive services ~$4,000 class [1][2] |
| 1991–92 manual snap-ring (trans J4A4-1003542–1005978) | Shifter moves fore/aft in 1st/2nd under load; crunch | Check transmission number, not just VIN | Failure means a transmission rebuild; cost not yet verified [3][4] |
| Aluminum body accident repairs | Uneven panel gaps, broken paint seams | Paint-depth gauge; inspect seams and shock towers | Specialist aluminum repair is expensive; many shops won't touch it [2] |
| Aging electronics / leaking capacitors | Dead climate display, stuck fan, cluster faults | Full function check; ask about recaps | Individual boards vary; stacked failures add up [1] |
Cost figures checked against the sources below in Nov 2026. Bracketed numbers refer to the source list.
Notes
- Aluminum body means rust is rare, but steel subframes and mounts still corrode — check them [5].
- NA2 (1997+) 3.2 and 6-speed are the ones most collectors want; early NA1 manuals need the snap-ring check.
