What we do · Leighton Buzzard

A full independent garage, plus the specialist stuff.

Servicing, repairs and MOT prep, performance and tuning, recommissioning and restoration, and pre-purchase inspections — on classic, American and modern cars. Frank’s a 40-year ex-drag-racer who handles the everyday and the hard-to-source alike: LHD big-block V8 Americana, rare classics, parts sourcing and fabrication. One master, hands-on — the car you book in is the car Frank works on.

In detail

The full service list, plainly put.

01 · Servicing, repairs & MOT

The everyday work a good independent garage should do well. Routine and manufacturer-schedule servicing, MOT preparation, fault diagnosis and repair across every system — on all makes, classic, American and modern. Over four decades on the tools means a problem gets found and fixed, not guessed at.

  • Servicing — routine and full manufacturer-schedule, all makes.
  • MOT — preparation, advisories explained, repairs done right.
  • Mechanical — engines, gearboxes, brakes, clutches, suspension, exhausts.
  • Electrical & diagnostics — carburettors to modern ECUs.

02 · Performance & tuning

Frank raced the quarter mile at Santa Pod in the late ’70s, and the tuning bench is where that heritage earns its keep. Fast-road and track builds, rolling-road and dyno tuning, and sensible upgrades — set up properly and proven on the rollers, not promised on paper.

  • Builds — fast-road and track, specced to how you actually drive.
  • Tuning — rolling-road and dyno, mapped and measured.
  • Upgrades — brakes, suspension, induction, fuelling, ignition.
  • Heritage — a drag-racer’s eye for where the gains really are.

03 · Recommissioning & restoration

Barn-finds and long-SORN cars brought back to the road — bodywork, welding and mechanical rebuilds as the car needs them. This is honest, drivable restoration, not show-only concours. You get a car you can use and trust, with the work explained and priced for what it actually needed.

  • Recommissioning — brakes, fuel, ignition, cooling, suspension refreshed.
  • Bodywork — welding, rust repair and panel work where it’s needed.
  • Rebuilds — engines and gearboxes rebuilt to drive, not to display.
  • Ethos — done properly, explained plainly, no surprises.

04 · American imports & specialist

The deep-end work most local garages turn away. Left-hand-drive, big-block V8 American cars are a specialism, and so are rare and hard-to-source classics. Where the part doesn’t exist off the shelf, Frank sources it — or fabricates it.

  • American — LHD and big-block V8 Americana, serviced and tuned.
  • Rare classics — hard-to-source and unusual cars welcome.
  • Parts — sourcing from the right suppliers, here and stateside.
  • Fabrication — made and fitted when nothing else will do.

05 · Pre-purchase inspections

Before you wire the deposit and book the transporter, Frank inspects the car in person — a thorough, honest assessment of structure, mechanicals, bodywork and paperwork. He travels to the car anywhere in the UK. You get a straight answer: walk away, or buy with confidence.

  • Honest — a thorough hands-on check, told to you straight.
  • Reach — UK-wide; Frank drives to the car.
  • Scope — structure, mechanicals, cosmetics and paperwork.
  • Outcome — a written report and a phone call, before you commit.
