PONTIAC LUXURY
BODY & CHASSIS
A solid chassis will protect older Pontiacs from catastrophic rust, but the frame needs to be checked for weakness around suspension locating points, chassis outriggers, the windscreen surround, turret edges, boot and internal floor-pans. Missing bumpers or peeling chrome will be expensive to replace or rectify. US suppliers have bars that should fit local models, but careful checking is wise to ensure you don’t pay costly freight for incorrect parts. Even in the USA, parts that were once relatively common have become expensive, including rust-free doors at $600 each and $1000 for bumpers to suit 1968 ‘hidden headlight’ cars. Convertible tops need checking for fabric damage and frame twisting.
ENGINE & TRANSMISSION
Everything beneath the bonnet of a 1960s Pontiac will be easy to acquire. The engines are under-stressed and only high mileages or serious neglect will cause major problems. After a test-drive listen for hissing or bubbling from the radiator. Oil leaks from the top section of the engine usually aren’t seriously expensive to rectify but be wary of drips underneath the engine which could be a main bearing seal. Stuttering and backfiring will likely be a timing issue or carburettor problem. The Powerglide transmission is old-fashioned but should shift smoothly. At speeds below 80km/h they should also accept a manual downshift to Low gear without shuddering or refusing to respond.
SUSPENSION AND BRAKES
Brakes are a real problem with these large, heavy cars. In good condition, the all-drum system with power assistance will pull the car up quickly and with minimal pedal pressure. Pressing on the pedal for 30 seconds while the engine is running will reveal hydraulic problems. Listen when the brakes are lightly applied for noise and vibration signifying binding shoes, out-of-round drums or warped front discs. 1960s RHD conversions would normally use new components as the cars were sold through dealers with warranty, however later or private imports can display dodgy engineering.
INTERIOR & ELECTRICS
Early-1960s Australian cars came with leather trim and returning these to original condition will be costly. Imports used a range of fabrics and vinyl which can be obtained from restoration suppliers or overseas. Basic models have little that can fail but check that the heater/ demister controls aren’t seized. Cars with power windows and seat adjustment and especially those that are air-conditioned can be suffering from age-related faults that involve significant cost to rectify. Check that all power-assisted items work and get quotes to fix those that don’t work before making an offer on a car.
