TR7: Engine: Dolomite 2.0 slant-four - adequate, not exciting. 105hp. Reliable if maintained. Timing belt service critical. Build quality: Variable - Speke factory (early) worst, Canley (late) better. Rust: Wedge shape traps water. Rear wheel arches, sills, floors, A-posts, door bottoms, hatch area. Convertible: Check hood frame, seals. Values: Long underrated, now rising. DHC worth more. Budget £1.5-3k annually.
