Buy a Facel Vega HK500 on a solid tubular chassis and the correct brake and engine spec first. Early drum brakes, rusty sills and a misidentified V8 are the surprises that rewrite the budget.
For this November 5, 2026 guide I read Car Collector International: Facel Vega HK500 guide and Classic Driver: Facel Vega HK500 Sleeping Beauty. The mechanical cautions below come from those pages; the order of checks and the questions for the seller are my own practical recommendations. Any price figures in those sources are market snapshots, not a valuation of the car in front of you. So, compare it with recent sales of the same specification and condition. I also kept the advice to things you can see, hear or ask for on a viewing day.
Verify the exact engine against the chassis
Car Collector International lists multiple Chrysler and DeSoto V8s across the Facel range and says to match the engine to the build documents. Classic Driver describes the HK500's large V8 and 140-plus mph potential. Wrong engine paperwork changes value.
Check whether it has drums or discs
Car Collector International says early HK500 cars used drums that drew poor press, with Dunlop discs optional from 1959 and standard from April 1960. Ask which setup is fitted before you drive it hard.
Hunt rust in the sills and floors
Car Collector International flags rust in sills, floors, rear arches and around the wraparound rear glass. Classic Driver notes the body and chassis are sizeable and parts can be hard to source. A lift inspection is non-negotiable.
Expect parts and chrome to be dear
Classic Driver says some parts are difficult to source and that handling and braking upgrades are common on cars used on modern roads. Car Collector International calls Facel-specific trim, glass and chrome expensive to restore correctly. Budget for that reality.
Ask about right-hand drive history
Classic Driver notes many UK cars came through H.W.M. and that right-hand drive was common even for some home-market buyers. That is not a fault, but the paperwork should match the steering.
Get a specialist to assess the structure
Car Collector International wants panel gaps, chrome originality and interior checked against period photos and Amicale records. Ask for written findings with local estimates rather than a handshake.
Read the Amicale record on convertibles
Car Collector International says convertibles are exceptionally rare across the FV and HK series, with one HK500 convertible noted, and that any open car must be checked against the marque record. Classic Driver adds that UK cars often came through H.W.M. as right-hand drive. Prove the body style before you bid.
Prove the identity before a deposit
Match the chassis number on the HK500 to the title, any import papers and the plate on the car before you order a history report. Our VIN verification guide walks through that match, and imported-car report coverage sets expectations for cars that spent years overseas. Older chassis numbers may sit outside modern report databases, so confirm coverage before paying. NMVTIS covers U.S. title history only; it cannot replace foreign records or a physical inspection.
Get the repair scope in writing first
If the sills are soft or the brake spec is unclear, get a Facel specialist's written estimate before you bid. Look, a seller PDF or a folder of photos is a starting document, not independent proof of condition. Ask the inspector for written findings with local estimates, split into safety work and cosmetic wishes. The NYC consumer-agency used-car guidance tells buyers to have an independent mechanic check the car, and our pre-purchase inspection checklist helps you set the scope. Keep a dated note of the drive, the temperatures and any noises, because a seller who disputes your findings later will ask what you saw and when.
We are a licensed CARFAX and AutoCheck reseller, not affiliated with CARFAX, AutoCheck or Experian. Guest reports have been about $5.50, member reports about $4.50 and a two-report bundle about $6.75; confirm the price at checkout because it can change. A report can miss unreported work, so keep the inspection appointment even when the history looks quiet.
