The Jaguar seems to be an XK140, successor to the world famous XK120. Top speed 120-125 mph, and given this was the roadster version, about 3350 produced, and only 49 to stay in the UK. These cars still sell for about $100,000.

Your first Bentley is, incredibly, the first Bentley model- the 3-Litre! Production started back in 1919 and ended in 1929. The green label cars were guarenteed to go 100 mph! With production numbers being 1,622 models, this is a super rare car with a price at one auction being $671,000!

Your 2nd Bentley is the first Continental model, released as an upgraded S-series model. Only 431 were ever produced, 164 right hand drive. These cars continue to sell for over $1,000,000!

^ Lotus Super 7, or one of its recreations like the Caterham Super 7.

Sorry for the long list, but I'm not great at classic cars.

Thanks!

Please help. This car is under a cover and I have seen it every week for several years but I never knew what it was.
What is this?! by carguyjt, on Flickr

I am going to guess this is a Porsche 914, but I could be wrong.

I don't thinks so. The back has that weird shape and the 914 doesn't have it.

Alfa Romeo Giulia TZ maybe? rear shape kind of resembles it

Look into seeing if it's a Saab Sonnet.

That is actually possible I will have to look at it closer next time I see it.

Not a sonett this is smaller.

Sonetts are tiny lol.

I know but if you see this in person this is incredibly small. as small as a lotus.
