Alfa Romeo 147 GTA (2002–2005) Price Guide

The Alfa Romeo 147 GTA is one of the great flawed hot hatches. A hand-built 3.2-litre Busso V6 producing 247bhp, all of it driving the front wheels, in a car that weighs 1,360kg. It is simultaneously magnificent and absurd — and that is precisely why people love it.

The Car

Launched in 2002, the 147 GTA used the 3,179cc version of Giuseppe Busso’s legendary V6 — the largest and final iteration of an engine family that began as a 2.5-litre in 1979. Each unit was hand-assembled at the Maserati Research Centre in Modena, with aluminium block, four valves per cylinder, and Bosch Motronic ME7.3.1 management. Power was 247bhp at 6,200rpm with 221lb ft at 4,800rpm, driving through a six-speed manual gearbox. A Selespeed automated manual was optional — 1,004 of the 5,029 total production were so equipped. The body was 43mm longer, 35mm wider, and 30mm lower than the standard 147. Walter de Silva and Wolfgang Egger at Alfa’s Centro Stile kept the visual changes purposeful but restrained: deeper bumpers, wider arches accommodating 225/45 R17 tyres, a subtle rear spoiler, and Brembo brakes with initially 305mm front discs (later upgraded to 330mm as standard after early cars proved under-braked).

The Differential Question

The 147 GTA’s defining weakness is its open front differential. Without a limited-slip diff, 247bhp through the front wheels produces torque steer under hard acceleration and terminal understeer on corner exit. A Q2 mechanical LSD was offered as an option but was never standard on any Busso-engined Alfa — despite what sellers may claim. Fitting a Q2 aftermarket transforms the car from a fast but frustrating front-driver into something genuinely exploitable. If the car you are looking at does not have one, budget for the retrofit immediately.

What Goes Wrong

The Busso V6 is fundamentally strong and good for at least 175,000 miles with correct maintenance. The first-motion-shaft bearing in the gearbox can fail prematurely — listen for a whine in neutral that disappears when the clutch is depressed. The planetary gears in the standard open differential break under hard use, which is another reason to fit the Q2 and remove the problem entirely. The ECU is mounted in the engine bay where heat can cause failure — a known design error that Alfa never corrected. Mass air flow sensors fail regularly, causing flat spots and rough running. Coil packs deteriorate with age. Front tyres last around 5,000 miles at best; less if you attempt to exploit the car’s performance. The CAN-bus network links every electronic system, and a fault on the data line is indicated by a flashing odometer — an Alfa-specific diagnostic quirk worth knowing. Rear suspension uses unequal-length radius arms that give a degree of passive rear-wheel steering, which makes the car more agile than its weight distribution suggests.

Buying

Always choose the manual gearbox. The Selespeed was slow and unreliable in the 147 and is best avoided entirely. Service history from a specialist — Alfashop or similar — is worth far more than a stamped book from a non-specialist dealer. Busso V6 cam variators rattle on cold startup; renewal is a four-figure job but neglecting it leads to worse. Giuseppe Busso himself died in 2006, just three days after the last engine bearing his name left the Modena production line. The 147 GTA shares its chassis and engine with the 156 GTA saloon and the GT 3.2, but the shorter wheelbase makes the 147 the sharpest and most demanding of the three to drive.
