Austin-Healey Sprite (1958 to 1971)

Why people buy one

• Light, nimble and huge fun at modest speeds, with a strong club and competition following.
• The Frogeye's face, with headlamps on top of the bonnet, makes it one of the best-loved small British classics.
• Simple A-series engines and running gear shared with many BMC cars, so mechanical parts are easy to find.
• Easy for a home mechanic to work on.
• Later cars added useful improvements: front disc brakes from 1962, semi-elliptic rear springs and wind-up windows on the Mk III from 1964, and the 1275cc engine on the Mk IV.

What to weigh up

• There is no separate chassis; the floor, sills and tunnel carry the strength, so structural rust matters more than cosmetic rust.
• Glassfibre Frogeye replicas were built in the 1980s and 1990s, and later Sprites and MG Midgets have been converted to look like Frogeyes, so a "Frogeye" must be checked against its chassis number and V5C.
• Many cars have replacement or uprated engines, gearboxes and brakes, so mismatched numbers are common and a car may not be the specification described.
• Glassfibre bonnets are common on Frogeyes; Classics World notes they usually make an otherwise original car less desirable.
• Cramped, noisy and draughty, with basic weather protection.
• The MG Midget, built alongside from 1961, is its badge-engineered twin, but it is a separate car and is not covered here.

Where they rust

• Inner and outer sills; the inner sill can be checked with a screwdriver through the bung in the outer.
• Rear spring mounting boxes and hangers; a gap of much less than about three inches between tyre and rear wheelarch may mean they have collapsed.
• Floors and footwells, especially where hood leaks let water collect.
• The joint between front wing, sill and A-post, where filler is often hidden, and the A-posts generally.
• The box section above the back of the sill over the rear wheelarch on later cars.
• Front bulkhead around the heater box, battery tray and master cylinder.
• Inner wings, engine supports and the crossmember under the radiator.
• Lower wings, wing seams, door bottoms and wheelarches, plus the Frogeye's bonnet hinges and seams.

Mechanical weak spots

• Engine: look for at least 40psi oil pressure when warm, listen for big-end rumble and check for blue smoke, leaks from the rear crankshaft seal and signs of head gasket failure.
• Cylinder heads can suffer valve-seat erosion on unleaded fuel; closing tappet clearances and lost power are the signs.
• Gearbox: first gear has no synchromesh, second-gear synchromesh wears early, and gears may jump out on the overrun.
• Rear axle: knocking can mean worn half-shaft splines; check for oil leaks.
• Front suspension needs regular greasing; check the kingpins, wheel bearings and lever-arm dampers, and look for stiff steering.
• Rear suspension: rusted or broken springs and worn bushes, particularly on the quarter-elliptic cars.
• Brakes are drums all round on the Frogeye; look for perished wheel cylinder seals, pulling and leaks. Wiring is simple but often aged.

At a Mathewsons viewing

• Check the chassis number against the V5C. The Austin Healey Club gives the prefixes as AN5 for early Frogeyes, HAN for later Sprites, GAN for MG Midgets and AAN for the 1971 Austin Sprite.
• On a Frogeye, check whether the bonnet is steel or glassfibre and whether the body details match the year on the V5C; ask a club before bidding on one you suspect is a replica or conversion.
• With a torch, look at the rear spring mountings, sills and floors from underneath, measure the gap above the rear tyres, and look inside the boot at the inner sills and rails.
• Lift the carpets and press the floors and footwells for damp or soft metal, and check the bulkhead and door hinges for movement.
• Open the bonnet and note the engine size and number; if staff start the car, listen for rumbles and watch for smoke, but do not assume it will be started.
