Manual or automatic?
The issue with building a rear/mid engined stick shift car is winding the manual shifter linkage round the engine - especially a wide one like a V8. The original Ford GT40's and their successors got around most of the problems by putting the actual shift lever to the side between the seat and the door. At least that reduced the number of u/j's required, but the linkage still had to get back to the rear of the car one way or another. And given the age of many Vette owners, having to clamber over a side mounted lever probably would not play that well! Back when I was in the vehicle engineering business in Europe, one company I was with experimented (and even went into production) with a cable operated shifter. We never achieved the "feel" expected from a proper shift linkage and the idea did not last.
To the OP: From reading comments here over the years from people looking to buy C5's, it definitely seems that MN6's are priced a bit above the autos. And of course they made less of them, plus the 6 speed was an extra (non trivial) cost item.
but I'll save the 40k it would cost for tires.

I avoided autos for years as they never seemed to get going like a stick shift. Finally cracked under "domestic pressure" a couple years back and bought a Genesis with Hyundai's own 8 speed with paddles. The paddles are almost redundant as this thing snaps off shifts quickly and does not get caught out. It really gets off the mark due to the wide spread across the 'box. My guess is they used the ZF as their benchmark.






Charlie442, my advice is you've got to decide what you want. Here's what I thought when I bought my C5.
The A4 has the advantage that all drivers can drive an automatic so the transmission is not an issue when selling, especially trading in the Vette. Also, over-revving by a previous owner is much less risk with an A4. Driving an auto in bumper to bumper traffic is much easier than the manual if you're going to make a DD out of the C5.
But after buying a 04 coupe with A4, it took about 3 years and the novelty of owning a Vette wasn't enough. To me the A4 became boring and I wanted more control over the transmission.
The manual is more fun, especially if you like to down shift and back off through the exhaust. There were fewer manual cars made in the C5 so a nice one might be a little harder to find. If you plan on modifying the engine, take into account that the M-6 is more robust and can handle a lot more HP. I was warned not to make major mods to my C5 unless I upgraded the transmission as well.
So I bought an A4, then 3 1/2 years later traded it for a C7, Z51 that's a (drum roll) MANUAL.
But that's me, you have to decide what's important to you for your C5.
Hadn't driven a manual for years, when I tried my first test-drive of an M6-equipped C5 a couple of weeks ago. I had a hard time leaving a stop without chirping the tires. (Perhaps I should have been "loud and proud" of that burnt rubber -- that's not something I can get out of my Prius.
)There are more M6 Vettes on sale in my area than there are A4 models. I do worry about clutch wear, though ... I know that replacing the clutch takes a lot of expensive labor. But I'm looking for a "road-trip warrior," something that will be flashy and fun on the open road and will show up well on the Coffee & Cars circuit. (And for now, I'm planning to keep the Prius for errands.)
Hoping to check out a 50th-Anniversary-Red coupe this afternoon, unless it's bought by the guy who's seeing it this morning. And it has a manual transmission. Give me a couple of hours of stop-and-go driving, and I'll surely recover my manual and pedal dexterity.

(On edit: Yep, the guy bought it. Oh, well ... Next ...)

I have the same car but with a few more miles on it, enjoy!
Sometimes I think I'd like to have an A4 convertible for leisurely driving and cruising and a Z06 for the twisties.
