I say go for what talks to you, i waited for about 3-4 years before having the money and truck availability sync up. i've only had it for 4 days now, and i thought my obsession would ease once i got it, but no, it's gotten worse (or better). One thing i can say is, definitely get what you want. i was going to buy an 85 shortbed that had a 91 front end on it, bucket seats, and lowered suspension, all of which i didn't want, but the price was right. 2 weeks later, i find my truck for about 400 dollars more. i avoided buyer's remorse by waiting.
