Getting my XPT Friday, insurance question

This is my first off road vehicle I’m getting insurance for (the others weren’t this expensive) so my question is, am I’m leaving something out with my coverage? I just got a quote for insurance (comp, collision and liability) with $100 deductible from my agent (Hartford) for off-road use only and a vehicle value of $25,000, which will be raised with customized parts when added, and my same limits of liability as my other vehicles, for only $168 for the year 😳 This just doesn’t sound right so I’m coming to the experts to let me know what I’m missing. I’m 53 with good driving record and multiple discounts with this company but it still sounds to good to be true. Help needed before I start putting miles on this beast.
Thanks for any input.
