Sell it to Bot and have his sister-in-law drive it down.

I replaced the mounts in a 2.5 turbo awhile back, I'm not sure but I think the mounting system is similar to the one used in your car. It was a very easy job - took about an hour as I recall. Much easier than the old W115 or W123 mounts.

It sounds to me like you've got the dreaded "new-car Jones" disease. If you want a new car and can afford it sell it and get what you really want. W124 E300D values seem to be quite high these days - you may be surprised what a nice example with 100K miles will fetch on the open market.
