The car was a reasonable success, but not as much as beleaguered BL had hoped.
It was Britain's sixth best selling car in 1983 and 1984, with more than 80,000 sales in its second year.
After the "boom" years of 1986 and 1987, Maestro sales went into decline.
An early reputation for poor build quality and unreliability did not help.
The biggest problems centred around the 1.6-litre R-series engine, which was a hurriedly modified BMC E-series engine from the Austin Maxi because the under-developed S-series unit was not yet ready for production.
R-series units suffered from hot starting problems and premature crankshaft failure.
This was particularly evident in the MG Maestro 1600, which was included in the original 1983 model range but discontinued the following year.

The new S-series engine eventually appeared in July 1984, and was fitted to all existing 1.6-litre Maestros.
The new S-series engine also came fitted with electronic ignition.
At the same time, some minor equipment upgrades were made across the range.
The 1.3-litre base model gained head restraints, a passenger door mirror and a radio.
The 1.3-litre HLE, 1.6-litre automatic and 1.6 HLS all gained a radio-cassette player.

In October 1984, there were more equipment upgrades made across the range.
The 1.3 base models gained reclining front seats, door bins, locking fuel filler caps and clocks.
The L models gained cloth door trim, upgraded upholstery, and remote-adjustable driver's side door mirrors; the 1.6 Ls gained five-speed gearboxes.
The 1.3 HLEs gained five-speed "4+E" gearboxes with overdrive fifth gear ratios, side mouldings, tweed cloth upholstery and  remotely adjustable passenger's side door mirrors.
The HLS and 1.6 automatics gained tinted glass, central locking, electric front windows, velour upholstery and upgraded radio-cassette players.
The MG Maestros gained electronic fuel-injected 115 bhp (86 kW) versions of the 2-litre O-series engine, uprated suspension and ventilated front disc brakes, colour-keyed exterior trim, tinted glass, central locking and leather-trimmed steering wheels.
The new MG Maestro offered much better performance and refinement than its predecessor.

Also in October 1984, the existing Maestro line-up was joined by the 1.3 HL and 1.6 HL.
These models fitted between the L and HLE models.

August 1985 saw the arrival of the 1.3 City and 1.3 City X. The 1.3 City was similar to the previous 1.3 base model.
The 1.3 City X added full carpeting, cloth upholstery, head restraints, a rear parcel shelf, a radio and a manually operated choke.
These models also did without the plastic bumpers, having more conventional steel bumpers with plastic end caps similar to the Maestro van.

The original dashboard was of a multi-piece construction, and gained a reputation for being flimsy and prone to squeaks and rattles, so in February 1986, this was replaced with the more conventional dashboard from the Montego and in the change the voice synthesis unit (prone to reliability issues) was dropped.
At the same time more minor equipment upgrades were made across the range.
The City X gained door bins and rear wash-wipe.
The L and LE gained tweed trim.
The HL and automatic gained velour trim and additional brightwork.
The Vanden Plas gained leather trim and uprated electronic stereo system.

BL was sold to British Aerospace in 1988, when the Austin badges were discontinued.
The range was sustained by the noisy but economical direct injection naturally aspirated Perkins diesel unit launched the previous year.
However, without a turbo this model was rather slow.
The diesel had already been available in the Maestro van since 1986.

The MG Maestro Turbo, fitted with a turbocharged version of the 2.0 fuel-injected engine from the MG Maestro EFi, was unveiled at the Motor Show in October 1988 and went on sale on 17 March 1989.
It was one of the fastest production hatchbacks in the world with a top speed of 129 mph (208 km/h), making it faster than the Ford Escort XR3i and RS Turbo, as well as the Volkswagen Golf GTI.
