Waiting isn't satisfying my addiciton, so I found a set of Cup I's (7Jx17 and 9Jx17 - ET55 - 965.362.128.00 & 965.362.124.00) on Craigslist from a '91 Turbo. Mobile wheel refinisher is stopping by tomorrow to see if he can pretty them up a bit.
Here the way I got them, and now that they've been cleaned up a bit. Yes they are a little rough, but local, authentic Cup I's I just couldn't let get away.

You have two convex surfaces intersecting. You can't solve it with ramps unless you'd go halfway out into the street. You need to create a tangency (or nearly), and since you can't work on the street, you really need to scallop out the driveway, probably 6-8 ft. in at a minimum, to create a concave that meets the street and then gradually slopes into the driveway grade going towards the house. That would work. Then you might have little drainage problem at the low spot, without a new drain. Ay ay ay...

Hey Laker. Still haven't figured out where to mount my County Corg license plate. I'ts still sitting on the mantle. Great looking conversation piece. Thanks again.
OK, having designed a few parking garages in my career, I can say that your driveway problem isn't so much the steep angle, but the "breakover", or transition between the the angle of the street and the drive. Basically, you have none. In section (profile), the street and drive are two straight lines that intersect. It looks like the drive was built after the street and they didn't even cut the curb, they just bridged up to the top of it with asphalt in the gutter.
The only way to correct the problem is to cut the curb out and rebuild a short section of the drive. I'm sure you're already in violation of the City or community's driveway standards with asphalt blocking the gutter. You would need to regrade the drive to result in a longer "s" curve, in vertical profile, between the street and drive. That would involve excavating the first 10' or so of your yard.
Having grown up in the country, the advice to cross the grade change at an angle was good advice. But you really can't accomplish a good "fix" of the drive problem without some serious pavement work.
My suggestion is to at least get an estimate for the work and see if you can't rationalize it as improvements that increase the value of your property. With the recession, you might get a surprisingly low price.
At the same time, you could get an estimate for the least expensive option, which would be to add an arched area of pavement out onto your lawn which would allow you to swing wide when entering/exiting and crossing the breakover at a sharper angle. An optional feature would be to add to the width at the curb line to give you a little more room to cross the curb at an angle.
Just my opinion. Good luck with your decision. Hope you don't just procrastinate on upgrading your car!

Thanks gentlemen, for the detailed analysis of my current landscape. I've got the numbers of two paving companies I've been meaning to call anyway to fix a runoff issue. Can't imagine how much this is going to pinch.
I don't think the pavement work will increase property values any. Property taxes most definitely, if they find out. The curb is actually cut out there, and we put that blob of asphalt along the the street to prevent normal cars from scraping. It was much worse before.
I would if he wasn't cross-country. Thanks for the name, though. everyone seems to be very happy with him

finished product....
First driveway guy came by to take a look and thought he could get me two more inches by lopping off the crest of my driveway and regrading down to the street.
Maybe I'll just lower the rear and nose-up upon approach. (joke, a bad one)

This was already mentioned, don't back in. Pulling in forward and backing out let's you cut in/out at sharper angles. Before you move, repave your driveway or add air ride, just try that ...

I'll take 'clearance pics' tomorrow backing out / pulling in. Thanks for the reminder. I have 1-1.5 cm clearance now at standard U.S. height. Afraid lowering will put me way under.

Thank you Rennlist!
I have similar driveway issues to Mike (Laker) and after my removing every milligram of glue for an RS interior refit, my C2 is now in the shop undergoing a transformation by the "Usual Suspects". This includes new suspension etc and lowering to Euro RS ride height.
Concerned about my driveway, I was able to enlist the help of as local 'lister (Tom Bennett) who has a beautiful C4 at RS height.
Using the wide angle/swing method, it is juuusssttt possible. Hurrah!
Thank you Tom for helping me out and thanks to Mike for starting this thread.

James,
Ha! ..... will do when I get her home.
Steve Weiner is doing a great job with the parts (as usual) but some of the goodies are on back order making it unlikely that my car will will leave Mr G's shop until mid June.
The excitement is killing me but I know when it's done, it will be done right
