Thinking of trading my 2019 Audi A3 for 1997 Silvia S14

I found a 1997 Silvia S14 for a good price. It's in very good condition with only 70,000 kilometers. The problem is, I currently drive a 2019 Audi A3 as my daily. In order to get the S14, I would need to trade in the A3. My A3 has 120,000 kilometers and is having issues with the transmission. If I trade it, I'll need to use the S14 as my daily driver.
