In short: Unprofessional, Unreliable, Dirty damaged old cars.
Quick Car Rental is not a real car rental company, its just some guys with some cars and a website!
Renting a car from these guys was a disaster to begin with.
No contact desk at the airport - you are required to call them for a "shuttle bus" (picked up in the car given)
No specific pick up location - was 30 mins waiting in a crowd outside the airport for a random guy in a car. Then driven to the back parking lot of a nearby hotel.
Business was conducted in the corner of the reception of that hotel, which was under renovation. They had no computers or equipment, everything was written on receipt paper and credit card payment was taken at the hotels actual reception desk, very unprofessional (I should have walked away at this point)
The condition of the car was very poor, (ordered a Ford Escape, got a Lincoln mkx) it had not been washed, several dents and scatches all over it. The dash board had some constant warning lights for tyre pressure and door opened which beeped constantly when driving. Key fob would not lock the doors it had to be done from inside the car and close the door quickly. Sunroof would open but not close!
My brother also rented a car at the same time (ordered a Ford Escape, got a Honda crv) similar condition, dirty with damage.
This is where the real un-professionalism comes out! We drove from Niagara falls to Niagara on the lake town a 30 min drive, we stopped for 10 mins and the Honda would not start up, I called the rental place at 2:30pm and asked them to send a mechanic he said it might just be the battery can i get jump leads? I said no i'm not from here I wouldn't know where to get them just send someone please.
At 3:50pm I called back for an update, he asked where was I located (I had explained that in the 1st call), he said he'll send someone.
At 5pm I called again he said there is a taxi on the way. I asked why is there a taxi coming? The taxi man has jump leads I would have to pay him $20 for the call out. (I almost lost it, i'll leave this explicit part out)
At 5:30pm a taxi pulled up, we explained the situation and didn't have to pay him he was kind enough and attempted to start the car but it didn't work.
Called back and told them to get a mechanic or a replacement car out here now.
At 6:50pm called again, no answer. 7:15 no answer, at 7:25pm he said hes waiting for a replacement car to be returned. I told him this is unacceptable we have been stranded here 5 hours with an 18 month old baby and two elderly parents we need a car now!
Several more unanswered calls up to 8:45pm he said someone is on the way, I demanded to know where he was and when he would arrive. His answer was "some time buddy, some time". (fyi Toronto was only 45mins away)
At 9:35pm he arrived, after a heated argument (obviously I was in my rights to be annoyed) he hooked up jump leads to the car and eventually got it started and proudly proclaimed "see I know my cars buddy I know my cars". To which I replied - "so you knowingly gave us a defective car with a defective battery"!
He then attempted to send us on our way with the Honda, my response was "oh no, we're taking your car, you go home in the Honda" (another argument ensued, we eventually left in his car at 10:10pm).
I dont think this is a real car rental company, its just some guys with a couple of cars I doubt they even have most of the fleet they claim.
Please avoid using this "company".
