On my old V8, there is no buzz, or sound.
On the new V8, there is a sound like a horn being powered for a very short time. I found out tonight that there is an alarm on the newer V8- it went off when I opened the boot.
So that answers that part.

In the upcoming strip of that car, I shall make notes of what is where, and see if anything matches up with the old car.

85 WR quattro
90 V8 Silver, 91 V8 Black, 93 V8 Lago
93 100e quattro V6. Titan, i think
