1 CLASSY CHASSIS
Though strong, the 100/4’s chassis can hide rust very well and needs to be inspected closely. Check the main chassis rails for evidence of accident damage or poor welding. Outriggers are prone to rot too; and don’t forget that the body is welded to the chassis, so the two can’t be easily separated as would be the case with, for example, a Triumph TR2.
2 DENT MY PRIDE
The bodywork is largely aluminium, which is vulnerable to dents. Examine the shell for signs of accident damage or filler and for rot where aluminium meets steel, and the bottoms of the A- and B-posts. Check body alignment and make sure the doors open and close easily.
3 ENGINE ANTICS
The four-cylinder engines are tough, but prone to oil leaks, silted-up waterways and water seepage between the cylinder head and block.
4 STEERING & SUSPENSION
The cam and peg steering boxes can leak oil (check the level regularly) and wear. The lever arm shock absorbers can also leak and work loose on their mountings. The rear axle is also prone to oil leaks, though replacing the seal is a relatively easy job, fortunately. Problems with overdrive tend to be restricted to the solenoid or associated electrics.
