TVR Chimaera 450 MK3 – 2001/Y
Late “Mk 3” car with the faired in headlights, darker dash veneer.
Full service history from new; all receipts bound in date order.
Had a new speedo at c18000 miles, fully documented throughout file.
All books, stamped service book, with both sets of keys / fobs.
Car is lovely inside and out, underneath and mechanically.
Some (usual) very small paint chips, particularly behind the wheels, otherwise exterior stunning, really good deep shine and no paint fade, certainly looks very fresh and tight.
Chassis is superb. Later powder-coating on these MK’s was excellent and this one has been kept on top off throughout its life. (Pics will follow).
Ian Davies at Sportmotive prepped the car for the last owner, in late summer 2018. It had been re-commissioned by Steve at SD Autotec prior to that after a period of storage; new battery, new radiator, discs, pads and quality tyres all round. Full service and drive shaft joints replaced.
This year it’s had a new starter motor, drivers door solenoid and fuel pump replaced (with an original spec Bosch one); plus recent full set of ACT silicon coolant hoses.
Recent oil and filter, gearbox oil and coolant change.
In 2019 the car visited Joolz at Kit & Classics twice, and had £5000 spent on it, new Emerald K6 ECU and new Stealth Cam kit were fitted, amongst other things. (See below for the blow by blow).
