Any deficiencies compared to "regular" Prius?

Other than worse fuel economy, I don't know of any.

 

Compare Side-by-Side

 

but they didn't make a v in the early 2,000's

 

you're probably better off. if they bought an early gen 3 and got the blown head gasket, they might blame you

 

I don't believe a v has any major flaw differences as compared to a standard Prius.
I'd look to model years 2015 -17 as the latest and greatest.
Fuel economy expect 40 overall.
Rear seats recline.
Storage/ luggage capacity is superior.
Driver comfort is good.
Softex fabric wells well.
Models 1,2,3 with 3 offering LED headlights & fog lights, BOSE stereo and sunroof as I recall.
2 is a good deal and for the comfort/ options so I'd skip the 1.
If I was to point out weakness I'd say:
Brake maintenance (which maybe the same as a reg. Prius) requiring maintenance/ inspection/ lubing of the pins more than a usual car plus a brake pad change seem to have a special procedure over a regular car.
The v is a box in cross winds.
Rear wheel alignment can be difficult.
I notice you live in Michigan.
Not sure of a v in a snow zone, so a 4 wheel drive may be an important consideration for you.
Yet, the v is still a good car.
Good luck in your decision.

 

I suspect it gets 10 MPG less than a Gen 3 liftback.
Top speed is 103 vs 115. I find it hard to believe this is an issue.

 

I find the MPG will vary depending on location and driving style. I frequently hit over 45-55 mpg throughout most of the year in New England. The V is 5.7 inches. Which the standard Prius is 5.5. The ground clearance isn't an issue for me and I've yet to get stuck in snow. I've driven through over 6 inches of snow and through blizzards and I haven't had any issues on my all season tires. I've driven on 1400 mile road trips, packed with luggage and driven around with 5 people in the car with no complaints about discomfort. Getting in and out both the front and back is easy for passengers and the driver; especially for the elderly. Ultimately, its a good car that you can't go wrong with if you pick the V. Sitting in a standard Prius compared to the V, you just can't compare the extra room you have with the V. I've transported so many large items in mine including; a 44 gallon water heater, plywood, a door with a screen door attached to a door frame, a queen size mattress in the back.

 

Rear brakes on the v incorporate a mini-drum brake, for parking brake function. If anything, that might be a plus: the regular Prius rear brakes have some gotcha's. Not deal-breakers, but you have to be on your toes.

Prius v Repair Manual is one I haven't managed to cadge so far, btw.
