So worked on cars for a fair few years and I've often thought. If I could take the best bits from different cars to build the most reliable and easiest car to work on what bits would I use?

It's only for giggles, so don't need to be to serious how all the bits will bolt together.

My idea of the best NORMAL family 5dr car.

E39 BMW Body- Awesome looks and big boot, just get Volvo to rust proof it.
K20 Honda Engine- Plenty of power,built proof and no cambelt.
MK1 Focus front subframe- Easiest clutch changelaugh
Pug 106 Rear Axle- Brilliant strong design and easy to drop out if needed.
MK1 Focus front brakes- don't even need to take off pad carrier to change discs.
Late 90's Honda rear drum brakes- yes not discs. Prefer drums to work on. Easy to adjust up and never have to hit drums to get off.
Saab interior - thinking like a 95, never sat in a uncomfortable Saab and always loved the "night mode" dashcool
Electrics- get the Japanese to sow in all the electrics.

That's my cocktail for my perfect normal family car!

Love to hear from other mechanics and their cocktailscoffee

Easiest clutch change.

Early vauxhall astra Cav, Nova

Drop the clutch out the bottom cover without removing the gearbox, start to finish, no more than 15 mins.

Gutted when they changed the design to omit the access cover.

I've heard about them but I've never changed one myself. Wish they were like that now

That clutch change idea deserve a Nobel prize, at the very least!

I’d add, get Lexus to build the thing.

Three brilliant pieces of mechanical design from my own cars as follows.

999cc Fiat FIRE unit in my Uno had a non-interference design, so when the cam belt snapped, there was no contact between the valves and the pistons. It just coasted to a halt. Why aren’t they all like this?

MG Midget fuel pump - two bolts into the cylinder block - total cost to change, less than a tenner in less than 10 minutes.

Lotus Eclat windscreen washer bottle - designed to lift out to refill, so no perilous over spill on the dodgy electrics.

We ran a taxi fleet almost entirely on the basis of this design feature.

Did one of those for a mate many years ago, he had been quoted 3hours labour, I told him we could do it an hour or so. He was shocked how easy it was and much a local clutch changing outfit were willing to rip him off for.

Datsun 240z , me and a mate pulled the engine out in 20 mins or so when we were young and daft , granted we had a block and tackle already set up but there was so much space under the bonnet and not much to disconnect.

Triumph spitfire- bonnet and arches lift out of the way giving unrestricted access to the engine and bulkhead. Front wheels are perfectly placed to sit on while working on the engine.

Cavalier’s were the same - I had a new one one that broke its belt 3 times.

Are we allowed to use bike bits? Most bike clutch changes require one cover removing and you're there. Can do it on the side stand without dropping the oil.

Non interference engines by their nature tend to run lower compression ratios so not really compatible with increasing specific output/economy

Book time was 1.2 hours as I recall, so yea quoting 3 was over the top, unless they didn't realise the correct way and were going to haul the gearbox out to do it.

Original Fiat Panda heater cores - in a plastic airbox held together with clips in the engine bay, probably the easiest ones to change of any car.

VAG cars and some others with the "service position" easily removeable front clip/crossmember for engine bay access.

Mercedes and some others where the bonnet can be opened to a second position even further up so you get much better access.

Whereas the Lotus Eclat wiper motor replacement is a complete dash removal eek

Unless you get a phone call, get distracted and forget to take the clips off......
Don't ask how I know.

Used to do that with my Herald. More often than I care to admit.

Also if the circlip holding the shaft in place wasn't fitted properly, and the shaft moves backwards , no drive.

Indeed!

Everything else was questionable- such as the load-bearing UJs on the rear suspension and the foam insert between the body and chassis which soaked up moisture and caused the chassis to rust. And the instruments lit by a teeny tiny light built into the roof….

Headlamps that allow bulbs to be changed easily without having to remove the battery, lamp unit, grille, bumper etc.

Dry timing belts with good access and a simple, easily adjustable, reusable tensioner.
