Yeah I have been able to find cheaper light bars and spot lights than the Narvas, though I wasn't quite sure if I needed the power of a light bar or if I could make a quality wiring setup either. I am more than happy to do the work myself, just don't have any experience. It would be really good if I could get it done in under $75, as the Narvas are quite expensive for me.
I've been having issues with my door locks, where if I lock or unlock the Echo with the key from the driver's door, all doors except the front passenger door will lock or unlock. Whereas if I lock or unlock the Echo with the key from the front passenger's door, all doors will lock or unlock. I am not sure what the problem is, though I think it may be the driver's door as sometimes it doesn't lock or unlock properly. I have found a few wreckers that have Toyota Echo sedans, and am planning on going as there are a few other bits and pieces the Echo needs replacing.
You are very right on good brakes and lighting, though I would add tires to that list as well.
It would be really great if you could provide some tips, I found a video where ChrisFix did a light bar install a while back (www.youtube.com/watch?v=b8GY69Ci7l4). I will probably end up installing a pair of spot lights rather than a light bar, to give the Echo a more rally look!
As for towing, I don't plan on any with the Echo, though a set of roof racks is probably something I'd look into in the future.
Hope you stay well and safe in these odd times!
