What would be a good trade in value on a 2002 Chrysler PT Cruiser Limited with no engine?

The question says it all. I took it to a dealer last night to trade in on a new car and the dealer offered $100 for it. I thought that was ridiculous. The inside is just about immaculate. Leather, sunroof, heated seats. I took some pictures on my phone just in case. The only problem is that the engine finally went out on it last week, so it needs a new one of those. What's your opinion? Thanks!
