Yes, not all tunnels needs to be walked thru, despite how far you've already gone in. You can always turn around..
The thing is with this one, it needs new paint (red), it is 5-speed and T-tops, but this one is has 216,000 miles on it. Which means I'd prob drive it til the motor died and then take 2-3 months to put an DE-T in there or VE if I am feeling brave (VE swaps are harder IMO)
but who knows, waiting to hear back from the guy
